Grab a cheap multimeter from your local store you can check fuses broken wires and voltages that will make it much easier to faulty find rather than shoot in the dark.
Also dont half *** it as you'll only have to repeat your steps and no one will be able to help you on forum.

When I said check drivers door wiring in rubber boot you said they where fine then later found one broken. Was it one of the thicker wires black or orange.
Black is negative orange is 12v its main power to doors.

If you did repair the black then double check the orange.

Also I get the impression electricals isnt your strong point when you replaced speakers did you cut joint any cables ?
More importantly did you have any issues with power windows locks before your speaker replacement.

Windows and locks worked perfectly fine, I put aftermarket speakers in, and boom, windows/locks won't work. Wouldn't have anything to do with me taking the dash out, because I replaced speakers, locks/windows stopped working, THEN I took the dash out to replace the heater core.

Check all the connectors in all 4 doors in both the boot that runs to the body and the connector to all your switches on the inside of the door panel, also I've had a wire break in the boot of the lift gate that caused the door locks to quit working, so it wouldn't hurt to check

I did not cut any wires.

Yes it was a thicker wire that was broken. It's a brown wire

Yes it could be that you disconnected something behind the dash

I have a feeling that although your door wiring was damaged it is not issue. Unless of course the black wire is broken too.

A circuit or wiring diagram plus a multimeter may be needed to track this down. If you can't find wiring diagram let me know and I'll try dig out something.

At a minium with ignition switch on the thick brown cable is 12v and black is negative.

I don't think you read my post correctly. Explain how it could be something that I disconnected behind the dash ?
My windows and locks worked fine, never had a problem. I take all my door panels off, replace speakers, put door panels back on, and then the windows and locks stopped working.
I tried to figure out the problems for a few hours and I couldn't, so I replaced my heater core.
Like I said before, the windows and locks were not working before replacing the heater core.

Anyways, I have not been on here lately. Fixed the window/lock problem.
There was a broken wire in the door boot on the passenger front door. added some wire in there with butt connecters and everything is working fine.
